A method of determining a mode of operation for a wireless terminal comprises determining a parameter indicating Hybrid Automatic Repeat Request, HARQ, re-transmissions in communications with the wireless terminal. The method further comprises determining a full duplex or half duplex mode of operation based on the parameter of HARQ re-transmissions.

According to one embodiment, a signal processing apparatus correlates a plurality of communication terminals as a group and enables one-to-many communications in the group. The signal processing apparatus includes processing circuitry. The processing circuitry assigns a transmission right to one of the communication terminals in the group. The processing circuitry generates text data based on voice data from said one of the communication terminals in possession of the transmission right. The processing circuitry gives a texting completion notice indicative of completion of texting processing to the communication terminals in the group. The processing circuitry transmits, after the texting completion notice is given, the generated text data to at least one of the communication terminals in the group.

A user equipment (UE) reports, to a base station, UE duplex communication characteristics. The UE then communicates with the base station in accordance with the reported characteristics. The characteristics can include duplex communication modes supported by the UE. The modes can include receiving and transmitting concurrently with the base station; communicating in a first direction with the base station and concurrently communicating in an opposite direction with a second base station; communicating with the i in a first direction concurrent with the base station communicating in an opposite direction with another UE; and communicating in half duplex (HD) with the base station in HD. The UE can receive, from the base station, a command to communicate in a reported mode. In such cases, communicating, by the UE with the base station, in accordance with the reported duplex communication characteristics includes communicating with the base station in the commanded mode.

Aspects of the present disclosure provide techniques configuring half duplex UEs (HD-UEs) to implement supplementary downlink (SDL) in band combination that may be in same or different frequency range designations (e.g., FR1 or FR2). Particularly, in order to compensate for the loss of downlink coverage and improve load balancing, aspects of the present disclosure configure the UE to perform random-access channel (RACH), a procedure that is a shared channel used by wireless terminals to access the mobile network, on the anchor carrier in time division duplex (TDD) band and after initial access, the UE may be configured to switch to SDL to receive subsequent downlink signals.

A method, system and computer program for transmitting at least two payloads in a downstream traffic phase of a time-division duplex (TDD) cycle with a single preamble from a headend followed by concatenated payloads without intervening preambles, whereby the payloads are ranked by increasing modulation profiles. The preamble, and concatenated and ordered set of payloads are then transmitted to two or more predetermined customer premise equipments (CPEs).

Certain aspects of the present disclosure provide techniques for autonomous beamforming configuration change. A method that may be performed by a wireless node includes determining a communication mode to be used for communication by the wireless node, wherein the determining of the communication mode includes determining whether the communication is associated with multiple simultaneous communications with one or multiple other wireless nodes. The method may also include determining a beamforming configuration to be used for the communication based on the communication mode, and communicating in accordance with the communication mode using the beamforming configuration.

A method for allocating resources by a Base Station (BS) in a wireless communication system is disclosed. The method includes configuring a Resource Block Group (RBG) dependent on whether a User Equipment (UE) operates in Full Duplex Radio (FDR) mode or Half Duplex (HD) mode, and allocating resources to the UE in units of the configured RBG. The RBG includes a plurality of Resource Blocks (RBs).
